during the first attempt I noticed that the screen was not actually turned off black it still had a wee bit of glow as if the device went to sleep. It occurred to me that the wipe is not failing but rather the screen is timing out at 50% (approx) and the process is still on going.

On the 3rd time I pressed the power button to restart the process again. I waited until 45% complete at that point I tapped the screen to bring up the % value and kept holding it or rather tapped periodically as not not let the screen time out...and guess what...the process was going on and I kept this up until the wipe was completed (only took about 10 minutes from that point.)

My theory is the screen time out at least on my device but the process is still on going I could attempt a new security wipe to test the theory but no wasted too much time on this.

Backup and running

First time I had one go over two hours... I simply stopped doing Wipes - Autoloader is good enough for me. It's a common issue, some have had it happen and it completed after days. Me, I'm not that patient.
